Python VirtualEnvrapper安装失败-“；什么会导致导入恐怖：没有名为“core”的模块；等

我在osx 10.6.8上，试图使用bash安装VirtualNVRapper，并且得到了神秘的反馈（至少对我来说是这样）。 我能够安装virtualenv

也许有人能给我指出正确的方向

失败安装的输出：

Downloading/unpacking virtualenvwrapper

正在为包VirtualNVRapper运行setup.py egg\u info

ImportError:没有名为core的模块

清理。。。 命令python setup.py egg\u info失败，在/private/tmp/pip\u build\u root/virtualenvwrapper中出现错误代码1

使用

pip install-U pbr

在/Users/admin/Library/Logs/pip.log中存储完整的日志

更新

pbr

包，全局解决了导入问题。

我怀疑这里存在版本控制问题-但到目前为止还没有尝试过的更新/安装将其修复python--版本返回python 2.7.4--可能存在配置我需要解决的问题？我想我会检查我的Mac环境设置，确保所有东西都使用Python2.7——最后几行似乎出于某种原因调用了2.6；我进行了pip安装，使pip2进入了2.7框架运行sudo pip install virtualenvwrapper结果下载了virtualenvwrapper-4.2.tar.gz您有什么收获吗？
